Getting paid twice, is that really going to enter the discussion, even as an analogy? The guy would be on north of $300k, how much perspective would teammates have lost to be concerned by a $100 supplement to his income?
I'd be stunned if any of Francis' teammates begrudged him for getting back into the swing of things by helping out with some basketball coaching.
When someone is in a cycle of what is clearly self-defeating or self-destructive behaviour in the way Francis is, at the end of the day he is a talented kid who is jeopardizing what would be a good AFL career at a minimum, it's about all of the objective confirmation that you need to know that he is clearly afflicted with some sort of mental health issue. It's especially the case when he is not going out and being a 'lad' and getting into trouble.
The only way I can see any of this becoming a problem is if Francis were to come back and then not be made to earn a game like everyone else does. The point at which he earns a game will depend on the condition he returns to the club in and the quality of VFL performances. If he returned in great condition and dominated a month of VFL footy I see no reason why he couldn't play. Either we're going to treat clearly mentally 'injured' people as injured or we're just stuffing around.
